SPECIFICATION forming part of Letters Patent No. 591,820, dated. October19, 1897.

Application filed December 4, 1896. Serial No- 614,471. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN G. CRONBACH, a citizen of the United States,residing at New Orleans, in the parish of Orleans and State ofLouisiana, have invented certain new and useful Improvements inBicycle-Supports; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to bicycle-supports, and has for its object toprovide a simple, cheap, and sufficient support for upholding bicycles,the same being adapted to be ap plied to any ordinary safety-bicycle andto be mounted on the seat-post tube, the said support being capable ofbeing folded compactly and to rest along the seat-post tube, so as notto interfere with the riders movements in propelling the machine.

To this end the invention consists in an improved support for bicyclesembodying certain novel features and details of construction, ashereinafter particularly described, illustrated in the drawings, andincorporated in the claims.

In the accompanying drawings, Figure 1 is 'a side elevation of abicycle, showing the improved support applied thereto and folded intoits inoperative position, also showing the operative position of thesupport in dotted lines. Fig. 2 is a detail perspective view of theimproved support detached from the machine and extended. Fig. 3 is adetail per spective view of the head-blockand clip by means of which thesupport is attached to a bicycle. Fig. 4 is a perspective view of thesupport folded, showing also a section of the seat-post tube of thebicycle. Fig. 5 is a detail view of the spring-clasp.

Similar numerals of reference designate corresponding parts in theseveral views of the drawings.

Referring to the drawings, Fig. 1 designates an ordinary safety-bicyclecomprising the usual diamond frame and having the inclined seat-posttube 2.

3 designates a bearing-block to which the improved support is adapted tobe pivotally connected, and this block is attached to the seat-post tubenear its upper end just under the seat-post cluster by means of asemicylindrical clip 4, which partially embraces the seat-post tube andis provided with oppositely and laterally projecting ears 5, throughwhich suitable fasteners 6 are passed into the block 3. The block 3 isprovided in that side which abuts against the seat-post tube with aconcavity or groove 7 for the reception of the contiguous face of theseat-post tube and is further provided with a depending lug or ear 8,through which extends a bolt 9.

The support proper is composed of two sections which telescope onewithin the other. The upper section (indicated at 10) is tubular for agreater portion of its length, and the lower section 11 is in the formof an extensionrod which slides within the section 10, so that thesupport as a whole may be extended or contracted in length. In order toprovide for the extension of the support, the section 10 is providedwith a longitudinal slot 12, which at its upper ends is extendedlaterally, as indicated at 13, to receive a headed stud or screw 14,projecting from the rod 11 and working in slot 12 as saidrod is drawnoutward from the tubular section 10 or pushed inward. The slot 12 at itslower end is extended laterally, as indicated at 15, and is alsoprovided with a short upward or longitudinal extension 16, forming asocket for the screw or stud 14 when the device is extended, saidportion 16 of the slot serving "to prevent the accidental folding ortelescoping of the support when in use. lVhen the rod 11 is pushedinward to its full extent and the screw or stud 14: moved laterally intothe portion 13 of the slot, the rod 11 is upheld and prevented fromaccidentally dropping. The rod 11 is provided at its lower end with anysuitably-shaped head 17 for engaging the ground or other surface uponwhich the bicycle rests. The tubular section 10 of the support isprovided at its upper end with an ear 18, which bears against the lug orear 8 of the block 3 and receives the pivotal bolt 9, being securedthereto by means of a nut 19. The block 3 is preferably arranged at thefront side of the seatpost tube, so that the support may swing outwardlylaterally therefrom to one side of the machine for supporting the latterat a slight inclination. Then the support is in its folded position, asindicated at Fig. 1, it is held by means of a spring-clasp 20, which forconvenience is constructed from a single piece of wire, the centralportion of which is looped or bent, as indicated at 21,to snugly embracethe tubular section 10, after which the terminal portions of thewire areextended upon each side of the seat-post tube, so as to frictionallyengage the latter, after which they are returned into the plane of thesection 10, and finally the extremities of said terminals are bentinward toward each other and inserted in sockets 22, formed at oppositesides of the section adjacent to its upper end, as clearly shown. Thisspring-clasp serves to hold the support firmly against the seatpost tubeby the pressure of the cheek portions 23 against said tube, as clearlyrepresented in the drawings, and the central or looped portion 21 ofsaid clasp is arranged to bear against the section 10 just beneath thestud or screw 1-1 when in its uppermost position, thereby producing astop for preventing the downward movement of said stud or 1 screw, andconsequently the rod or lower secf tion 11 of the support. I

The device is susceptible of changes in the a form, proportion, andminor details of construction, which may accordingly be resorted towithout departing from the spirit or sacrificing any of the advantagesof the invention. i

Having thus described the invention, what I claim as new is 1. Abicycle-support consisting of a telescoping support proper having asliding eX- tensible member, provision whereby said support may beextended longitudinally, a

clip to which said support is pivotally at-;

tached and which provides for the attachment of the support as a wholeto one of the machine-frame bars, and a spring-clasp 0011-; nected tosaid support and adapted to triotionally engage the frame-bar, and'atthe same time to engage a stud on the slidingmemberof the support so asto prevent the support becoming accidentally extended, substan:

tially as described.

2. Abicycle-support consisting of a tubular section having alongitudinal slot at each end with lateral ofisets or extensions, and anextensible section provided with a projecting stud working in the slotof the tubular section and adapted to engage in said lateral offsets,attaching means for pivotally connecting said support to the frame of abicycle, and a clasp connected to said support and adapted to engagewith the machine-frame for holding the support folded, and also adaptedto coact with said stud, substantially in the manner and for the purposedescribed' 3. A bicycle-support comprising a tubular section providedwith a longitudinal slot, and an extensible section telescoping thereinand provided with a stud projecting through and working in said slot inthe tubular section, means for connecting said support pivotally I tothe frame of a bicycle, and a spring-clasp pivotally connected to saidtubular section and provided with a'central portion which embraces saidsection and cooperates with said stud for preventing its downwardmovement, said clasp also comprising spaced cheek portions adapted tobear frictionally against one of the frame-bars of the machine,substantially in the manner and for the purpose specified.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
